The Conceptual Development of Quantum Mechanics Max. Jammer
Publisher: MGH

While few physicists will be surprised that all three loopholes have now been closed, doing so could be an important step towards developing failsafe quantum cryptography. One of the fundamental concepts of quantum mechanics suggests that particles like photons have properties of both waves (like radio waves) and particles (like concrete objects). As a photon particle travels, its electric and magnetic fields vary, but are Artur Eckert, in a 1991 paper, used Bell's Theorem and quantum entanglement to develop a quantum channel over which a key can be securely shared. It has led to a number of surprising results in the application of thermodynamic concepts to small systems, with many contributions by workers in statistical mechanics. In thinking about this question over the last few years, I started to notice that a number of subtle, non-intuitive concepts that I learned many years ago as a physics student seem to apply to the world of big data and information-based predictions in highly complex systems. But eventually it became clear that all these various projects had grossly underestimated the difficulties of developing any kind of AI system based on logic programming and deductive reasoning. For the historical significance of Schrödinger's work see Max Jammer, The Conceptual Development of Quantum Mechanics (1966). To me, the alleged path interference or superposition in the double slit is a different conceptual problem to that of the collision (or not) of QM (and nature) with local-realism. The loophole-closure experiment has been carried out .. If this is to continue, conceptual and technical advances harnessing the power of quantum mechanics in microchips will need to be investigated within the next decade. Quantum mechanics triumphs once again. These two Letters are important early contributions to the development of quantum cryptography, the use of the properties of quantum mechanics to provide secure keys for encrypting communications. For further discussion of these results and of additional .
